Nested Chimney Adapter for Cross-Diameter Locking and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chimneys with different diameters and mounting interfaces are not cross-compatible, leading to installation inefficiencies and potential gaps that may not comply with regulatory standards.
Innovation Solution
An adapter system with a radial adapter portion and locking interfaces that connects a female end of one chimney to a male end of another, including an inner sleeve and clamping ring to ensure a secure, leak-resistant, and high-temperature-resistant seal, allowing for compatibility between otherwise incompatible chimney sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adapter is used to connect incompatible chimney sections, then cross-compatibility between different chimney types is achieved, but the assembly height increases
Solution Approach 1:
The adapter is designed with a nested structure where an inner adapter portion is positioned within an outer adapter portion. The first locking interface (engaging the first chimney section) and the second locking interface (engaging the second chimney section) are nested concentrically, allowing the adapter to achieve cross-compatibility while minimizing the overall height increase by utilizing radial space rather than adding significant axial length.
2Reliability
If a secure seal is provided to prevent leaks and resist high temperatures, then reliability is improved, but device complexity increases
Solution Approach 1:
A sealing element is introduced as an intermediary component between the adapter and the chimney sections. This sealing element mediates the connection by providing the leak-resistant and heat-resistant seal, thereby improving reliability without significantly increasing the complexity of the adapter structure itself. The sealing element handles the complex requirements of high-temperature resistance and leak prevention.
Solution Approach 2:
The adapter incorporates composite material construction, combining materials with different properties to achieve both structural integrity and thermal resistance. The adapter may use composite materials that provide both mechanical strength for structural support and thermal resistance for high-temperature environments, thereby improving reliability while avoiding the need for separate complex components.

AI summary
An adapter and adapter system for connecting a female end of a first chimney portion to a male end of a second chimney portion. The adapter includes a first radial adapter portion with a first inner surface and a first outer surface extending along a first axis and wherein the first inner surface and the first outer surface are substantially coaxial. The adapter further includes a first locking interface protruding outward from the first outer surface and configured to engage with a first locking interface of the first chimney portion and a second locking interface protruding inward from the first inner surface and configured to engage with a second interlocking interface of the second chimney. The first outer surface of the adapter is configured to be received within the female end of the first chimney portion and the inner surface is configured to receive the male end of the second chimney.
